FIELD OF THE INVENTION

The present invention relates to a cosmetic composition and method for making up and/or enhancing the appearance of a keratinous substrate, comprising at least one supramolecular polymer, at least one detackifying ingredient which is a hyperbranched functional polymer, at least one fatty phase ingredient(s), at least one light silicone fluid other than the fatty phase ingredient(s), at least one copolymer containing a silicone resin segment and a fluid silicone segment and at least one functional filler. The compositions of the present invention may optionally contain at least one wax and at least one colorant.

DISCUSSION OF THE BACKGROUND

In general, when women use a makeup product, especially a foundation or lipstick, they wish this product to have good wear and transfer resistance properties.

With regard to this expectation, one or more polymers are typically employed to improve these properties. Illustrations of these polymers include silicone resins, polyacrylates and lattices.

However, the above-mentioned polymers, which are advantageous in terms of wear and transfer-resistance properties, are often found by consumers to be uncomfortable with regards to their initial application (difficult to spread and tacky feeling) and/or after application (tautness, mask effect). In addition, silicone resins provide no shine and moisture to the lip.

Unexpectedly, the inventors have found that it is possible to overcome this drawback by combining certain supramolecular polymers with a hyperbranched functional polymer, a light silicone fluid and a copolymer containing a silicone resin segment and a fluid silicone segment. In addition, the inventive compositions demonstrate high and long-lasting shine, and long wear of color compared to other silicon resin containing lipsticks on the market. At the same time, the inventive compositions provided an even film deposit, a good comfort level, and more moisture on the wearer's lips.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a cosmetic composition for making up and/or enhancing the appearance of keratinous substrates containing, in a cosmetically acceptable medium:

-   -   a) at least one supramolecular polymer,     -   b) at least one detackifying ingredient which is a hyperbranched         functional polymer,     -   c) at least one fatty phase;     -   d) at least one light silicone fluid other than (c);     -   e) at least one copolymer containing a silicone resin segment         and a fluid silicone segment;     -   f) at least one functional filler;     -   g) optionally, at least one wax; and     -   h) optionally, at least one colorant,

wherein the supramolecular polymer is based on functionalized polyalkene polymer of formula HO—P—OH in which P represents a homopolymer or a copolymer that may be obtained by polymerization of one or more linear or cyclic polyunsaturated C₂-C₁₀ and preferably C₂-C₄ alkenes, further wherein said one or more linear or cyclic polyunsaturated C₂-C₁₀ alkenes may be branched, further wherein said supramolecular polymer may be derived from the reaction, especially the condensation, of said functionalized polyalkene polymer with at least one junction group functionalized with at least one reactive group capable of reacting with the reactive group(s) of the functionalized polyalkene polymer, the said junction group being capable of forming at least 3 hydrogen bonds, preferably at least 4 hydrogen bonds, preferentially 4 hydrogen bonds, and wherein the composition provides good wear, high and long-lasting shine, and transfer resistance properties in a less tacky manner.

According to another aspect of the present invention, there is provided a method of making up and/or enhancing the appearance of a keratinous substrate involving or comprising applying onto the keratinous substrate the above-disclosed composition, wherein the composition provides good wear, high and long-lasting shine, and transfer resistance properties in a less tacky manner.

DESCRIPTION OF THE INVENTION

Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term “about” which encompasses ±10%.

“Keratinous substrate” may be chosen from, for example, hair, eyelashes, lip, and eyebrows, as well as the stratum corneum of the skin and nails.

“Polymers” as defined herein, include homopolymers and copolymers formed from at least two different types of monomers.

As used herein, the expression “at least one” means one or more and thus includes individual components as well as mixture/combinations.

The “wear” of compositions as used herein, refers to the extent by which the color of the composition remains the same or substantially the same as at the time of application, as viewed by the naked eye, after a certain period or an extended period of time. Wear properties may be evaluated by any method known in the art for evaluating such properties. For example, wear may be evaluated by a test involving the application of a composition to human hair, skin or lips and evaluating the color of the composition after a specified period of time. For example, the color of a composition may be evaluated immediately following application to hair, skin or lips and these characteristics may then be re-evaluated and compared after a certain amount of time. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions.

“Tackiness” as used herein refers to the adhesion between two substances. For example, the more tackiness there is between two substances, the more adhesion there is between the substances. To quantify “tackiness,” it is useful to determine the “work of adhesion” as defined by IUPAC associated with the two substances. Generally speaking, the work of adhesion measures the amount of work necessary to separate two substances. Thus, the greater the work of adhesion associated with two substances, the greater the adhesion there is between the substances, meaning the greater the tackiness is between the two substances.

Work of adhesion and, thus, tackiness, can be quantified using acceptable techniques and methods generally used to measure adhesion, and is typically reported in units of force time (for example, gram seconds (“g s”)). For example, the TA-XT2 from Stable Micro Systems, Ltd. can be used to determine adhesion following the procedures set forth in the TA-XT2 Application Study (ref: MATI/PO.25), revised January 2000, the entire contents of which are hereby incorporated by reference. According to this method, desirable values for work of adhesion for substantially non-tacky substances include less than about 0.5 g s, less than about 0.4 g s, less than about 0.3 g s and less than about 0.2 g s. As known in the art, other similar methods can be used on other similar analytical devices to determine adhesion.

“Substituted” as used herein, means comprising at least one substituent. Non-limiting examples of substituents include atoms, such as oxygen atoms and nitrogen atoms, as well as functional groups, such as hydroxyl groups, ether groups, alkoxy groups, acyloxyalky groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen containing groups, ester groups, thiol groups, sulphonate groups, thiosulphate groups, siloxane groups, and polysiloxane groups. The substituent(s) may be further substituted.

For the purposes of the invention, the term “junction group” means any group comprising groups that donate or accept hydrogen bonds, and capable of forming at least three hydrogen bonds and preferably at least four hydrogen bonds, preferentially four hydrogen bonds, with an identical or different partner junction group. These junction groups may be lateral to the polymer backbone (side branching) and/or borne by the ends of the polymer backbone, and/or in the chain forming the polymer backbone.

In one particularly preferred embodiment, the supramolecular polymer of the invention corresponds to the formula (I) below:

wherein n can be an integer from 20 to 70; most preferably an integer from 30 to 40. Preparation Process

The polymer according to the invention may be prepared via the processes usually used by a person skilled in the art, especially for forming a urethane bond between the free OH functions of a polyalkene, and the isocyanate functions borne by the junction group.

By way of non-limiting illustration, a first general preparation process consists in:

optionally ensuring that the polymer to be functionalized does not comprise any residual water;

heating the said polymer comprising at least two reactive OH functions to a temperature that may be between 60° C. and 140° C.; the hydroxyl number of the polymer possibly serving as a reference in order to measure the degree of progress of the reaction;

adding, preferably directly, the ureidopyrimidone junction group bearing the reactive functions, especially isocyanate such as those described in patent WO 2005/042 641; especially such as the junction groups having the CAS numbers 32093-85-9 and 709028-42-2;

optionally stirring the mixture, under a controlled atmosphere, at a temperature of about 90-130° C.; for 1 to 24 hours;

optionally monitoring by infrared spectroscopy the disappearance of the characteristic isocyanate band (between 2500 and 2800 cm⁻¹) so as to stop the reaction on total disappearance of the peak, and then allowing the final product to cool to room temperature.

The reaction may also be monitored by assaying the hydroxyl functions; it is also possible to add ethanol in order to ensure the total disappearance of the residual isocyanate functions.

The reaction may be performed in the presence of a solvent, especially methyltetrahydrofuran, tetrahydrofuran, toluene, propylene carbonate or butyl acetate. It is also possible to add a conventional catalyst for forming a urethane bond. An example that may be mentioned is dibutyltin dilaurate. The polymer may finally be washed and dried, or even purified, according to the general knowledge of a person skilled in the art.

According to the second preferred mode of preparation, the reaction may comprise the following steps:

Step (i)

Functionalization of the polymer, which has preferably been dried beforehand, with a diisocyanate according to the reaction scheme: HO-polymer-OH(1 eq.)+OCN—X—NCO(1 eq.)→OCN—X—NH—(O)CO-polymer-OC(O)—NH—X—NCO.

The diisocyanate may optionally be in excess relative to the polymer. This first step may be performed in the presence of solvent, at a temperature of between 20° C. and 100° C. This first step may be followed by a period of stirring under a controlled atmosphere for 1 to 24 hours. The mixture may optionally be heated. The degree of progress of this first step may be monitored by assaying the hydroxyl functions.

Step (ii)

Reaction of the prepolymer obtained above with 6-methylisocytosine of formula:

This second step may optionally be performed in the presence of a cosolvent such as toluene, butyl acetate or propylene carbonate. The reaction mixture may be heated to between 80° C. and 140° C. for a time ranging between 1 and 24 hours. The presence of a catalyst, especially dibutyltin dilaurate, may promote the production of the desired final product.

The reaction may be monitored by infrared spectroscopy, by monitoring the disappearance of the characteristic peak of isocyanate between 2200 and 2300 cm⁻¹. At the end of the reaction, ethanol may be added to the reaction medium in order to neutralize any residual isocyanate functions. The reaction mixture may be optionally filtered. The polymer may also be stripped directly in a cosmetic solvent.

According to one particular mode, the said supramolecular polymer is dissolved in a hydrocarbon-based oil, which is preferably volatile, in particular isododecane.

Thus, the composition of the invention will comprise at least one hydrocarbon-based oil, which is preferably volatile, in particular at least isododecane, especially provided by the supramolecular polymer solution.

In particular, the supramolecular polymer(s) may be present in a composition according to the invention in an amount ranging from about 1% to about 60% by weight, preferably from about 3% to about 45% by weight, more preferably from about 5% to about 20% by weight, based on the total weight of the composition.

In another particular embodiment of the invention, a makeup composition is in the form of a lipstick and the supramolecular polymer(s) may be present therein in a content ranging from about 1% to about 40% by weight, preferably from about 3% to about 30% by weight, more preferably from about 5% to about 15% by weight, based on the total weight of the composition.

Hyperbranched Polymers

Hyperbranched polymers are molecular constructions having a branched structure, generally around a core. Their structure generally lacks symmetry, the base units or monomers used to construct the hyperbranched polymer can be of diverse nature and their distribution is non-uniform. The branches of the polymer can be of different natures and lengths. The number of base units, or monomers, may be different depending on the different branching. While at the same time being asymmetrical, hyperbranched polymers can have: an extremely branched structure around a core; successive generations or layers of branching; a layer of end chains.

Hyperbranched polymers are polymers that are highly branched and contain large number of end groups. Hyperbranched polymer usually contains a central core and the growth of the polymer emanates from this central core. The growth of the polymer is made possible by repeating units of single monomers or linear chains added onto the central core. The end unit of the single monomer or linear chain can be functionalized which can become junction points (i.e., linkage points) for further growth of the polymer. The final form of the hyperbranched polymer exhibits a tree-like structure without any symmetry or regularity.

The synthesis of hyperbranched polymer can be produced by single monomer methodology (SMM) or double monomer methodology (DMM) (Gao and Yan, 2004). For SMM, polymerization involves an AB_(x), AB* or a latent AB_(x) monomer through generally four different types of reaction mechanism: polycondensation of AB_(x) monomers, self-condensing vinyl polymerization (SCVP) self-condensation ring opening polymerization (SCROP) and proton transfer polymerization (PTP). For DMM, a direct polymerization is possible with two types of monomers or monomer pairs, the most notable being the polymerization of “A₂+B_(n), n≧2”, and the couple-monomer methodology (CMM) has also been used.

There are several ways to characterize the topology of a hyperbranched polymer, such as, by its degree of branching and the Wiener index. The degree of branching is defined as B=2D/(2D+L) where D is the number of fully branched units and L is the number of partially reacted units (Holter et al., 1997). For a completely linear polymer, B=0 and for a fully branched hyperbranched polymer B=1. The Wiener index states the sum of paths or branches between all pairs of non-hydrogen atoms in a molecule (Wiener, 1947). It is defined as W=½_(j=1) ^(Ns) Σ_(i=1) ^(Ns)d_(ij) where N is the degree of polymerization and d_(ij) is the number of bonds separating site i and j of the molecule. For two polymers with equal number of molecular weight, the linear polymer will have a smaller Wiener number than the hyperbranched polymer.

An end group can be reacted with the hyperbranched polymer to obtain a particular functionality on the ends of chains.

Hyperbranched Functional Polymers

“Hyperbranched functional polymers” refers to polymers comprising at least two, for example three, polymeric branches, forming either the main branch or a secondary branch, and each comprising at least one at least trifunctional branch point, which may be identical or different, and which is able to form at least two at least trifunctional branch points, different from and independent of one another. Each branch point may be, for example, arranged in the interior of at least one chain. The branches may be, for example, connected to one another by a polyfunctional compound.

For example, certain branches may be hydrophilic, i.e. may predominantly contain hydrophilic monomers, and other branches may be hydrophobic, i.e., may predominantly contain hydrophobic monomers. Further branches may additionally form a random polymer or a block polymer.

As used herein, “at least trifunctional branch” means the junction points (i.e., linkage points) between at least three polymeric branches, for example n polymeric branches (wherein n=3 or more), of which n−1 branches at least are different in chemical constitution and/or structure.

For example, use of the functional filler can improve one or more of the following properties of the composition: mechanical, thermal, barrier, scratch resistance, UV absorption and solvent permeability. In addition, or alternatively, the use of the functional filler can simply reduce the cost of the composition. Functional fillers are also classified by the chemical families, physical structures (which could be irregular, acicular, fibrous, or plate-like in shape, form or size), and inherent properties of the compounds. They are generally rigid materials that are immiscible in the bulk in molten and solid states and will exhibit distinct dispersed morphologies. The most commonly used functional fillers in the industry include but are not limited to: talc, calcium carbonate, mica, kaolin, nylon fibers, cellulose fibers, fumed silica, clay and amino acid based powder (e.g., lauroyl lysine).
